Ultra Long Range DDLmesh Wireless Mesh/Data Link OEM/ODM Module from China Suppliers & Factory for HD Video Transmission
The new DDLmesh series wireless digital data link is a low-cost long-distance video & data transmission product featuring a small size, light weight, 2×2 MIMO, complete functions, and abundant frequency bands. Based on the SDR (Software Defined Radio) platform, the DDLmesh series utilizes Beamforming, Maximal Ratio Combining (MRC), Maximal Likelihood (ML) algorithms, Low Density Parity Check (LDPC) coding, intelligent frequency selection, and autonomous frequency hopping technology to deliver exceptional RF performance and robust anti-jamming capabilities.
This advanced data link radio provides ultra-long distance, low latency, and bidirectional multi-channel network video, data, and voice integrated wireless transmission. Utilizing the world's leading code-modulated physical layer waveform technology, alongside flexible anti-jamming and secure encryption designs, it serves as a highly reliable remote data link solution for UAVs, helicopters, robots, unmanned ships, unmanned vehicles, and special vehicles.
System Composition
The application system is primarily composed of the airborne radio (connected to the airborne camera) and the ground radio (connected to the ground computer), along with necessary accessories including the power supply, antenna feed system, connection lines, and connectors.
Key Capabilities
Simultaneous Transmission
Supports simultaneous transmission of three IP/HDMI/SDI/CVBS HD video feeds alongside multiple two-way transparent data channels (such as flight control/pod, BD/GPS, and voice).
Secure Encryption
Integrated AES encryption ensures robust transmission security across all connected nodes in the unmanned field.
High Output Power
Transmission power of the station can reach up to 40W, providing a consistently stable and highly reliable communication link.
